Abstract: A headlight for a vehicle includes a light source. The light source includes: a substrate; a light emitting diode chip; and a phosphor. The phosphor through which light exiting from a light emitting surface penetrates. The phosphor includes an exiting surface through which the light from the light emitting surface penetrates and exits. A first direction of the exiting surface corresponds to a height direction of a light distribution pattern by the light exiting from the exiting surface, and a second direction of the exiting surface corresponds to a spread in a lateral direction of the light distribution pattern. A dimension in the first direction of the exiting surface is smaller than a dimension in the second direction of the exiting surface.

Abstract: A lamp module includes a drive circuit; a first light source; a second light source; and a switching circuit configured to receive a switching signal for indicating switching between a first function and a second function, and to control a first switch and a second switch such that the first switch is in an on state and the second switch is in an off state while the first function is indicated, the first switch is in an off state and the second switch is in an on state while the second function is indicated, and both the first switch and the second switch are in the on states at a time of switching between the first function and the second function.

Abstract: A vehicle lamp includes a planar light-emitting structure having a substrate on which an organic EL emission element is provided, a framing member that fixes the planar light-emitting structure inside a vehicle-lamp light cabinet, and an elastic member that is interposed between the planar light-emitting structure and the framing member and that fixes the planar light-emitting structure by its biasing force.

Abstract: A planar light emitting body 6 configured to emit a first illumination light, and a semiconductor light emitting element 7 configured to emit light toward the planar light emitting body 6 are disposed in a lamp chamber 5 defined by a lamp housing 2 having an opening and a cover 3 that covers the opening. The planar light emitting body 6 includes a transmitting layer through which light is caused to pass, and a control layer configured to irradiate light as a second illumination light by controlling a travelling direction of the light that is emitted from the semiconductor light emitting element 7 and passes through the transmitting layer.

Abstract: Provided is a construction machine in which the weight of a top plate of an aftertreatment device mount is reduced without reducing the rigidity of the top plate. In a construction machine where a vehicle body frame for mounting an engine is equipped with an aftertreatment device mount for supporting an exhaust gas aftertreatment device, a mount top plate of the aftertreatment device mount includes a support on which the exhaust gas aftertreatment device is placed, a pair of outer walls extending parallel, a groove portion parallel to the outer walls, a connecting portion provided on the support, and an upper reinforcing member orthogonal to the groove portion at a position of the connecting portion. The upper reinforcing member includes a first reinforcing portion for reinforcing the connecting portion and a second reinforcing portion to be fitted in the groove portion.

Abstract: A lamp unit has an organic EL panel in which an organic EL light emission portion is formed on a substrate, the organic EL panel being flexible, and a frame that fixes the light emission device so as to cover a light emission area of the organic EL, panel. The frame has a window or a transparent portion at least in a part of a portion, overlapping the light emission area, of the frame. The frame is formed with recess portions at both ends thereof to house both end portions of the organic EL panel.

Abstract: A light emission device includes an organic EL panel and a molding resin. In the organic EL panel, an organic EL light emission portion is formed on a substrate. The organic EL panel is flexible. The molding resin shapes the organic EL panel so that the organic EL panel is in a curved state.

Abstract: Provided is a construction machine having a central foothold and a maintenance access passage with high safety. The construction machine includes an upper slewing body including: an upper frame, an engine compartment, a cabin on a right or left region of the upper frame, a central foothold immediately forward of the engine compartment and on a central region of the upper frame widthwise of the upper frame, and a maintenance access passage extending rearward while elevated to guide a worker from the ground forward of the upper frame to the central foothold on a side opposite to the cabin. Widthwise of the upper frame, an inward edge of an upper end portion of the maintenance access passage is located inward of one edge of the central foothold, to thereby form a transit zone between the maintenance access passage and the central foothold.

Abstract: A marker lamp mounted on a vehicle includes a light source unit (7) including an organic EL element (10). The light source unit (7) includes a first light emitting part (12a) for emitting red light of a first wavelength band and a second light emitting part (12b) for emitting red light of a second wavelength band different from the first wavelength band.
